2020-02-12ASoC: sgtl5000: Improve VAG power and mute controlOleksandr Suvorov
VAG power control is improved to fit the manual [1]. This patch fixes as minimum one bug: if customer muxes Headphone to Line-In right after boot, the VAG power remains off that leads to poor sound quality from line-in. I.e. after boot: - Connect sound source to Line-In jack; - Connect headphone to HP jack; - Run following commands: $ amixer set 'Headphone' 80% $ amixer set 'Headphone Mux' LINE_IN Change VAG power on/off control according to the following algorithm: - turn VAG power ON on the 1st incoming event. - keep it ON if there is any active VAG consumer (ADC/DAC/HP/Line-In). - turn VAG power OFF when there is the latest consumer's pre-down event come. - always delay after VAG power OFF to avoid pop. - delay after VAG power ON if the initiative consumer is Line-In, this prevents pop during line-in muxing. According to the data sheet [1], to avoid any pops/clicks, the outputs should be muted during input/output routing changes.
